 -install the BMC2 (Ref. AMM TASK 36-11-34-400-001)
 -refer to Para. 4.C.

 (b)
 If no sensing element is damaged:

 -disconnect the connector between the cable 2HF2 and the sensing element 1HF2
 -connect the LOOP CONTROLLER (9240SI) between the connector 1HA2-AA/6B and the ground
 -do a check of the impedance read on the LOOP CONTROLLER (9240SI).
 1_ If the impedance is less than 3 KOhms:
 - replace the CABLE-CONNECTING, ENG 2 PYLON (2HF2) (Ref. AMM
 TASK 36-22-15-000-001) and (Ref. AMM TASK 36-22-15-400-001)
 - do a check of the impedance read on the LOOP CONTROLLER
 (9240SI).
